In the FREE to fly standard, what does the 'F' stand for?

• A. Rested sufficiently
• B. Free of any symptoms which can lead to sickness or incapacitation
• C. Eaten before the duty
• D. Enough time has elapsed since consumption of alcohol or medication

Answer: (B)

F stands for being free of any symptoms which can lead to sickness or incapacitation. The idea is that a crew member must not be showing signs of illness or conditions that could impair their ability to perform duties. Symptoms like nausea, dizziness, chest pain, fever, severe fatigue, or confusion can affect judgment, reaction time, or the ability to handle an in-flight emergency, so they must not be present. The other parts of the FREE to fly standard (rested sufficiently, eaten before duty, enough time since alcohol or medication) address other factors that can affect performance, but they are separate from this particular requirement.
